基于磁性金属颗粒膜Kerr磁光效应的关系，结合电子跃迁和自由电子共振模型及实验数据，分析了金属颗粒膜的磁光Kerr旋转和Kerr椭偏现象，由分析研究表明：在磁性金属颗粒材料中Kerr旋转和Kerr椭偏率光谱（ Kerr效应）中的共振峰不是由单一电子的跃迁引起，其中由于等离子体激化元的存在，而引起的等离子体共振行为在此产生了相当的影响．亦即对磁光Kerr旋转和Kerr椭偏率起作用的是电子跃迁与自由电荷载流子的等离子共振相互作用共同引起的．这一结论与对较大Kerr效应的4 f化合物的相关实验强烈的Kerr效应和明显的共振结构相一致，这在铥原子化合物（ TmS， TmSe）和铈化合物（ CeSb， CeSb0.75 Te0.25， CeTe．）及L10 FePt膜中都已观察到这一现象．

Based on the magnetic-optical Kerr effect and model of the electronic transitions with resonance and experiment data in magnetic metal composite media, it shows that the resonant peak in the magnetic-optical Kerr phenomena of the Kerr rotation and Kerr ellipticity spectra is caused not only by the electronic transitions, but also the plasma resonance which has rather a large influence, i.e, it is attributed to interaction of both the e-lectronic transitions with the plasma resonance of free charge carriers on the magneto-optical Kerr effect en-hanced.This conclusion is consistent with the strong Kerr effect on experimental of 4f compounds(such as TmS, TmSe and CeSb0.75 Te0.25 , CeTe, L10 FePt thin films) and resonance structures.
